rmnovnn @As-GENERATOR..

The Schedule referred toV in those'Lette Patent and' making part 'of the canne.V

To-cll whom it mag/'concern a new and 4useful Improvement in Gas-Generatore.

and I do'.hereby declare` .th'at the following is a full, clear, and exact description thereof', which will enable those s killed in the art tomake and' use the same, reference being had, to -the accompanying drawing forming part of i this specification.

This invention relatesto 'improvements in apparatus .for producing illuminating gasv by carbureting vatmospherclair; and

The invention consistsllirst. In the arrangementof the liquid-regulator, with relation to the Vcarlmreter and an ordinary gasmeter, whereby-a uniform" pressure of air is obtained, and the 'same level of liquid maintained in the earbureter and liquid-regulator.

Second. In `the construction of the air-regulating vessel, and `its arrangement with relation to the'vcare bureter, distributing-pipe, 'air-"pipe, and gasometer, whereby the air, or gas from the gasometer is irected tothe carbnretegand .the "gas from the carbureter diluted' with air, ina more'4 simple and expeditious manner. than heretofore; 4and it-bonsists, lastly, in the general arrangement-of parts to lproduce an economical and compact apparatus.

The drawing represents a longitudinal elevationI of the'apparatus, witlrfparts of the different sections broken jaway to show thefconstructionand operation.

1 A represents afnfordinary f Clegg?.7 gas-meterfin its internal arrangement, .by which the necessary quantity of air is forced intotlie airfholder B O is the carburetiug-ohamber, containinga cylinder, O', which revolveson aprforatedhollowshaft, D,`through which `the carburetedair (or gas) is discharged, as indicated by the arrows.

rE isthe oill or liquidfregulator for supplying the cylinder C with auniform quantity of liquid. `F isa pipel ou the'topoffE', which connectsl with the liquid-reservoir above. f y

gis a'valve `in the bottonroffthis pipe, `which Vis operated byfa-iloat, h,'-through the lever L A regular'and constant4 4supply of; liquid is v maintained inE by the risingand falling-of the float, and the liquid having an outlet-pipe, J vwhich discharges the liquid into the carburetiug-chambcl @fthe liquid is maintained/in the chamber O attire samelevelas itisinEf f f Theair enters` tliejforciu'g-.chamber or meter A through .the pipe,]t`, l where itf is broughtv in contact with the water in A,aud i'sdischargedfinto 'the airholder'throug `jthe orifice 1, and the pipe seen in dotted lines'l';and'alvemrilioe in. v

i dlhe air-holder B. contains wate1,aud.the construc-V f y I tion is similar to that of the ordinary gasorneter, B being the. cistern, and Nit-he gasholder proper.

The valve atm is operated by N, andjs opened and closed according .to theprssure produced.

From N theair is conveyed into the chamber O, `throughthe pipe -P, (seen partly in dotted lines.)`

The chamber' Os the lower part of a vessel marked q, which is divided into three compartments.

VThe compartment R is in communication with the earbureter 0, through the pipe S, and the compart ment T is iu communication with-the pipe U, through which the gas or carburetedair is' Adischarged to the bur-ners. A A

`'.Ihrough the partition there are two valve-orifices, V V', with valves to fit, attached to a weighted' bar, w, which is hung on a pivot, w'.

The position of this bar and of the valves is controlled-by a cord, y, which.y is attached to the bar, as seen, and extends upward into the apartments of the building above," as may-be convenient or desirable. i

As seen in 4th edrawiug`,V isclosed, andall the air which enters thechamber O is'discharged through V, and intothe carbureter through the pipe S. l

.Whenever the air becomes tooiieely charged. with carbon and itis found ynecessary or expedient to llilute the gas,.the valve V'is lowered, by drawing. upon the cord which admits-oi' ailow of air into uthe pipe U, through theV short pipe as indicated .by the 'arrows. g

f -The course `of the air, as it enters the carbnretingchamber Gand cylinder O', is also indicated by arrows.

The cylinder C 1s provided with'a series of wiregauze or perforated diaphragms, a, which diaphragms are covered (upon one or-both sides) with annel, felt, or other good absorben't,'so that, Ias 4the cylinder is revolved, they takejfup the carbureting liquid, and become saturated? therewith, lthus exposing a very large surface for che airwhich is brought in-contact therewith, and charged with the vapor ofthe liquid.

After the air has passed through and by nearly all thediaphragms, it entersthe hollow shaft-D, through 'to the burners, as before stated.

C lfisapipe, which connects the carbureter with vthe liquid-regulator E, forthel purpose of keeping up an equilibrium of pressurebet-ween the two.

11" is an overflow-pipe for the carbureter.

Y c is a pipe for drawing oli' .any water of condensation whichm'ay accumulate in the air-pipe k. j' 1isa pipe'for drawing the water from A. 'E The movable partsrofthe apparatus are actuated by. a weight,=the cord ofjwhichis wound on thedrum G, iiom the shaft of which drum motion is imparted .to the vshaft H of the' vessel AV by gear-'wheels orpulleysfand may be most convenient or desirable.

'orifices 2, and-passes into-the pipe, u; for distribution.

Instead of a weight, a. spring may be used for actnating the shafts or moving parts of the apparatus.

By this apparatus the air becomes thoroughly charged with the vapor of the hydrocarbon liquid, and its richness in carbon or its illuminating power is at all times under perfect control through the valve arrangement iu the air-regulating vessel q.

I do not claim anything novel in the air-meter A, nor in the air-holder N, as I am aware that such parts are common; but

That I do claim7 and desire to secure by Letters Patent, is-

1. The combination of the gasoline self-regulating device E F g h 't with diaphragmcd carbureter C C', as set forth..

2. The arrangement of the gas-discharger in the shaft D of the diaphragmed carbureter C C'.

3. The combination of discharging-pipeu, chamber I z, and valve v with an air-chamber, to graduate the strength of gas, in the manner described.

4. The air-vessel V, composed of chambers R O T, valves v e', and lever u, operating as and for the purpose specilied.
